Summary: [4.7 Regression] ICE in mem_loc_descriptor due to
typed DWARF stack changes
Product: gcc
Version: 4.7.0
Status: UNCONFIRMED
Keywords: ice-on-valid-code
Severity: normal
Priority: P3
Component: debug
AssignedTo: jakub@gcc.gnu.org
ReportedBy: jakub@gcc.gnu.org
/* { dg-do compile } */
/* { dg-options "-g -O2 -msse4" } */
#include <x86intrin.h>
__m128
foo (__m128i x)
{
__m128i y;
y = _mm_cvtepi16_epi32 (x);
return _mm_cvtepi32_ps (y);
}
ICEs in mem_loc_descriptor, as we are asserting SIGN_EXTEND/ZERO_EXTEND will
have integral mode, while it has vector mode here.
